United States v. Stewart
907 F.3d 677
2d Cir.2018Background
- Sean Stewart, a former JPMorgan and Perella M&A banker, regularly disclosed material nonpublic deal information to his father, Robert Stewart; Robert and associates traded on that information and realized profits (~$1.15M total).
- A recorded conversation between Robert and cooperator Richard Cunniffe contained a reference (the "silver platter" statement) suggesting Sean said he had "handed [it] ... on a silver platter," which the government relied on to prove Sean intended his father to trade.
- Robert later gave post-arrest statements to the FBI offering alternative characterizations of the same exchange (attributing comments to bragging, drinking, or different wording), and he ultimately pleaded guilty to one conspiracy count; Robert invoked the Fifth at Sean's trial and did not testify.
- The district court admitted the silver platter statement (as against penal interest and possibly as co-conspirator evidence) but excluded Robert’s post-arrest FBI interview excerpts that Sean sought to use to impeach the silver platter statement.
- A jury convicted Sean on all counts; on appeal the Second Circuit vacated and remanded because excluding Robert's post-arrest FBI statements for impeachment was error that was not harmless, while noting the co-conspirator rationale could support admitting the silver platter statement on retrial.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Admissibility of Robert's "silver platter" statement | Government: admissible (penal-interest and co-conspirator exceptions) and central to proving Sean's intent | Stewart: contested hearsay/admissibility and sought to impeach it with Robert's FBI statements | Court assumed admissible for argument; indicated co-conspirator rule would support admission on retrial but did not decide hearsay fully because reversal turned on impeachment exclusion |
| Permissibility of using Robert's post-arrest FBI statements to impeach the silver platter (Fed. R. Evid. 806) | Gov't: statements not inconsistent and admission would be cumulative/harmless | Stewart: FBI statements materially differed and were admissible to impeach the silver platter statement | Court held exclusion was erroneous: FBI statements were inconsistent in tenor and bore on credibility; should have been admitted to impeach |
| Fifth Amendment privilege / refusal to compel or immunize Robert | Gov't: no duty to grant use immunity; no overreach or discriminatory immunity practice | Stewart: sought immunity or compulsion because Robert would provide exculpatory, noncumulative testimony | Court: district court did not abuse discretion—no evidence government engaged in overreach or discriminatory immunity; Fifth invoked properly; immunity not required absent extraordinary circumstances |
| Harmless-error assessment of excluding impeachment evidence | Gov't: error if any was harmless given overall strong case and other evidence | Stewart: error was not harmless because the silver platter was central and impeachment could have undercut intent finding; jury was not emphatically certain | Court: exclusion was not harmless—the silver platter was central and impeachment could have materially affected the jury's view of intent; conviction vacated and remanded for retrial |
